The slaying victims are 39-year-old Stephen Stay, his 34-year-old wife Katie and their four youngest children, ranging in age from 4 to 14. They'll be buried in a private ceremony after services Wednesday afternoon at their Church of Jesus Christ of Latter-day Saints in Houston.

The family was a member of the Mormon church. A top church official was expected to speak at the funeral service, according to a church news release.

The couple's 15-year-old daughter, Cassidy Stay, survived the attack a week ago by playing dead, called police and identified her uncle, 33-year-old Ronald Lee Haskell, as the gunman. Haskell had been divorced from Katie Stay's sister and records show he had a history of domestic violence.
